Abstract
Description
- The invention relates to a hose clamp, preferably for the closing of catheter extensions, in accordance with the preamble of claim 1.
- Hose clamps of this type are already known. EP 0 995 461 A1, for example, thus describes a hose clamp which comprises an integral plastic body which extends in an elongate manner and has two arms connected to one another at the ends. At their inner sides, the two arms each form a projection such that the projections are disposed opposite one another in the closed state of the hose clamp and are dimensioned such that they pinch off the hose. Both arms can be hooked to one another in the closed state. The hose clamp has respective openings at its front and rear ends via which a hose, for example a catheter extension, can be received.
- Such hose clamps are used, for example, on catheter extensions in the field of peritoneal dialysis. The clamp is located at the abdominal connector of the patient and serves the opening and closing of the catheter extension located at the abdominal connector. Since the clamp is in permanent contact with the skin of the patient, skin irritation frequently occurs due to the burrs and edges which are present with the already known clamp and with other commercially available clamps which are generally suitable for this use. The size and the shape are also perceived as irritating by the patient.
- The object of the present invention comprises further developing the already named hose clamps such that they are no longer perceived as irritating in wear by the patient.
- The object is solved in accordance with the invention by a hose clamp having a feature combination in accordance with claim 1. Accordingly, the hose clamp practically has the shape of a cylinder with cut-off sides, with it tapering conically at both sides toward its ends and with the ends being adapted to the circular shape of a hose to be inserted. The idea of this new shape of the hose clamp comprises the fact that the basic form is derived from a cylinder and that the ends are configured to taper conically. To make possible a comfort in wear which is as large as possible, the shape of the hose clamp is adapted to the shape of the hose.
- Advantageous aspects of the invention result from the dependent claims following on from the main claim. Accordingly, all edge regions of the hose clamp are rounded so that sharp edges and corners are avoided.
- In accordance with a preferred embodiment, the length of the hose clamp does not exceed ten times the hose diameter. It is furthermore advantageous for the radii of the rounded plastic body to lie between R20 and R100.
- It is furthermore advantageous for the plastic body to run out towards its ends at an angle of 5 degrees to 40 degrees to the longitudinal axis. A continuous transition from the hose to the clamp is hereby possible. In accordance with another preferred aspect, the outermost point of the hose clamp in the closed state is a maximum of twice the hose diameter away from the center of the hose to be inserted. A slim shape of the hose clamp is hereby defined which is no longer perceived as irritating by the patient.
- For easier handling capability, gripping surfaces are cut out at the otherwise substantially cylindrical outer surface of the two arms.
- The hooking mechanism is advantageously formed, on the one hand, by a projection facing toward the free end of the arm at the end of the hose clamp and, on the other hand, by a contact edge formed at the free end of the arm. In this context, a gripping surface is formed above the projection at the free end of the hose clamp via which the resilient end of the hose clamp can be deflected out of the latching position into a release position. It is hereby ensured that the hose clamp can be closed and opened a multiple of times.
- Further details and advantages of the invention result with reference to the embodiments shown in the enclosed drawings. There are shown:
-
FIG. 1 : a side view of a hose clamp in accordance with the invention; -
FIG. 2 : the side view ofFIG. 1 with a section line A-A drawn in; -
FIG. 3 : the section A-A ofFIG. 2 ; -
FIG. 4 : a view from the front of a hose clamp ofFIG. 1 ; -
FIG. 5 : a plan view from above of a hose clamp ofFIG. 1 ; and -
FIG. 6 : a section B-B in accordance withFIG. 5 . - A
hose clamp 10 in accordance with an embodiment of the present invention is shown inFIG. 1 . Thehose clamp 10 comprises an integral plastic body extending in an elongate manner and having twoarms 12 and 14. The arms are connected to one another at anend 16 of the hose clamp, with them being shaped in the unloaded state such that the arm 14 is deflected by the angle α with respect to thearm 12. Thearms 12 and 14 each haveprojections end part 16 in the direction of thearm 12 and can be hooked with theend part 22 in the closed state. The hooking mechanism is formed, on the one hand, by aprojection 24 facing the free end of the arm at the end part of thehose clamp 10 and, on the other hand, by a contact edge 26 formed at the free end of the arm. Respective mutuallycorresponding inclinations 28 and 30 are arranged at the front end of the contact edge 26 and at the corresponding end of theprojection 24, said inclinations having the result that when the arm 14 is pressed down, theend 22 is deflected out so that the contact edge 26 comes to lie below theprojection 24 so that hose clamp is hooked in the closed state. - A
gripping surface 32 is additionally formed at the free end of the hose clamp and theresilient end 22 of the hose clamp can be deflected via it out of the latching position into a release position. - As can in particular be seen from
FIG. 4 , respectivecircular openings 34 are provided in the region of thefront part 22, but also, as not shown in any more detail here, in therear part 16 and the hose or catheter is introduced into the hose clamp through them. - The
hose clamp 10 has a shape almost approximated to the shape of a cylinder with cut-off sides. The cylinder tapers conically toward bothends respective ends arm 12 in accordance withFIG. 3 . - As can in particular be seen from
FIGS. 5 and 6 , flattened portions are formed in each case at the periphery at thearms 12 and 14 as grippingsurfaces
